MAMARONECK - A small gathering in Harbor Island Park listened to civic and religious leaders speak about coming together to stand up against the hatred that's fueled a recent rash of violent and — oftentimes — deadly incidents.

Former village mayor Norm Rosenblum rattled off several mass killings that ended with Wednesday night's bar shooting in California that took the lives of 12 people.

Current Mayor Tom Murphy said, "Unfortunately, we have to have this vigil."

"Hate will not win here," Murphy said to a crowd of about 50 people on a chilly Thursday night. "We're a community built on diversity, and we will protect that."

The vigil was organized by Mamaroneck's Amy Siskind, a liberal author and critic of President Donald Trump, to "celebrate inclusion and unite against hate."

"This crime and violence against each other is something we all have to be vigilant of," Siskind said.

Siskind had been planning this event for almost two weeks. Last week, she posted on social media that she was going to hold an anti-hate event to let Proud Boys founder Gavin McInnes, who lives in neighboring Larchmont, know "that we are inclusive and repudiate hate."
